ABSTRACT:
An optical scanning apparatus that includes a light source, a polygon mirror for deflecting a plurality of light beams emitted from the light source, and an image focusing system for causing the light beams deflected by the polygon mirror to form spots on surfaces of a plurality of photosensitive drums, wherein the image focusing system is disposed between the polygon mirror and the photosensitive drums, and includes scanning lenses for causing the beams deflected by the polygon mirror to form spots on the respective surfaces of the photosensitive drums, and the central axes of the scanning lenses are spaced a predetermined distance from optical axes extended from the center of the light source.
